The fibonnaci sequence is nature's numbering system. This sequence appears everywhere in nature, such as the leaf arrangement in plants, the pattern of the florets of a flower, and the scales of a pineapple. And it's all because plants just grow in the most efficient way for strength, in a spiral pattern.
This spruce's immature pine cone captured our attention because of its colour. Who knew that an immature cone could be anything other than green or brown or anything in between? It also just happens to be another wonderful example of mathematics in nature.
